Until proven otherwise, the "Unitrex Datatime Monte Carlo" is the Holy Grail of all WWG`s as the "Magnavox Odyssey" is
the Holy Grail of all Video Games Consoles/Systems. I wanted one for a couple years when i saw the silver one but was hard
to find until i discovered which company released it.

"An on-the-wrist gambling casino is the latest feature to be packaged into an LCD digital watch. Based on a random-number generator in the watch circuitry, three games are available simply by pressing a Game and a Display switch: Jack Pot, Dice, and Roulette.

Jack Pot displays three random numbers, from 1 through 6, to simulate the three spinning wheels of a slot machine. Dice displays two random numbers from 1 to 6 to imitate the roll of a pair of dice. Roulette winds up with a number from 1 to 36, as in the spinning of a roulette wheel. The watch is appropriately named the Monte Carlo. Gaming, timing, and other functions are controlled by four switches on the watch by Unitrex in New York City. One switch, the normal time display, is also used in playing the games. A second is the Game switch, which selects the three games.... A Light switch turns on back illumination for night viewing, while a Set switch is used to set the time.

All three games use the same pseudo-random generator.... In the Game modes, the normal timing logic is locked out and the random numbers are displayed."

Personal note: All three games are rudimentary compared to Nelsonic or Casio ones, but it is the very first
watch to have a game , in fact to have three games. Just remember that in 1977, it was the invasion of so
many Pong consoles and the beginning of programmable video games.
